About September

September is the 9th month of the year and the 1st month of fall. Leaves turn color, acorns drop, the days get cooler and shorter. It’s magically sweater weather.

Top Consumer Spending Events

Back to College and Back to School shopping wind down on Labor Day weekend. These two top consumer spending events come in 2nd and 3rd on the National Retail Federation’s (NRF) list of top annual consumer spending events, right after the winter holidays.

Once September 1st rolls around, we see that plans for celebrating Halloween begin ramping steadily up. Halloween comes in 10th on NRF’s list.

View the planners below for insights and resources:

September Symbology

Playing off September symbology is a great way to offer personalized birthday gifts.

  • September’s birthstone is the sapphire.
  • Its birth flowers are the forget-me-not, morning glory, and aster.
  • The zodiac signs for the month of September are Virgo (maiden) until September 21 and Libra (scales) September 22 onwards.
The boughs of the oak are roaring inside the acorn.
– Charles Tomlinson

Regarding the Holidays and Occasions We Have Chosen

Our goal in creation of these calendars is to make marketing planning easier. So, in order to keep things simple we have chosen to focus on the top 12 consumer spending events as identified by the National Retail Federation; U.S. Federal Holidays; significant religious, ethnic, and cultural holidays that represent the diversity of the U.S. population as identified by ADL; and popular hashtag holidays that provide an opportunity for a natural business tie-in.

If you are interested in finding more occasions to commemorate here are a few resources:

Note that Bahá’í, Jewish, and Islamic holidays begin at sundown the previous day and end at sundown on the date listed.

Stay focused and on schedule with your marketing efforts.
